Patented May 22,` 1945 warmt oorrrlatol.V rolt 'roman 'rnNns y y nennen svi'rsky, Glendale, Calif; e Application ctolex# 19, 1942, Serial No. 462,522 i l 2` Claims.

Thisinvention relates to al valve water control for toilet' tanks. f

An important object oi the invention is to reduce the number of parts heretofore required in structures of the kind to which the invention pertains whilein no wise detracting from `eiliciency of operation, but on the contrary rendering the device of amore durable character and less apt to get out of' yorder when subiected to' a long continued use. In these particulars the present invention lis an improvement upon the water control for closet tanks described and claimed in my application Serial No. 43'l,0l7`, led February lo, 11942, of which this is a continuation-impart and which issued as U. S. Patent No; 2,299,767 on October 2'0", 1942. e In the present invention onefspeciiic improvement pertains to the provision, in combination with the structure with which itcooperates; of a simplified one-piece valve seat member which can be manufactured at a low cost` and which `can with ease be' removed after becoming wornand then as easily' replaced with a new part duplicating (exceptior wear)` the' part removed.

Another object of the i" ventionis to provide, `as an article of manufacture a headed, tubular, externally screwthre'aded valve seat member which may be used in a variety of valve structures.

With the foregoing and other objects in view,`

the inventionresides in the novel arrangement and combination of parts and thedetails of construction hereinafter described and' claimed, `it being understood that changes in theprecise embodiment off the inventionherein disclosed may be made withhi the scope oi' thatr whichis I claimed withoutdeparting from the: spirit of the invention.

Referring terne drawing wnereinis shown a preferred embodiment of the inventiom Fig.` l is, a cross section of a tcilet-tankshowing the installed device ina position lor flushing, Fig. Z-"is' an enlarged fragmentary view partly in side elevation and partly in vertical mid-sec tion of the upper portion oi the ball cock structure per se shown in Fig. l,

Fig. 3 is a transverse section taken on line 3--3 of Fig. 2, a `portion of the re-ll tube being ineluded in the view,`

Fig. 4 is a transverse section taken on line 4-4 of Fig. 2, and, Fig. 5 isa. perspective view of the combined screw and washer gasket per se.

Referring in detail to the drawing, the numeral 4 indicates a toilet tank containing a body of water 5 which is discharged through the x- (ICI. 137-404) ture 6y in a direction indicated by' the arrow when the valve 'I is' operate by meansy of a conventional trip lever through the medium of' the lift 8f in tile well known manne1'.` Pin overli'owpipe connectswith the iixture 6 at a `lower level than the seat or the valve 1v and into the mouth or said pipe is directed the free end of the re-fdl tuberi.

A pressurey source oi' water supplyj communicates with the tank 4, it being connected to the 11o inlet pipe II and the latter pipe being sealed in relation to the flo-or of the tank; The-discharge end portion of the pipe II is shaped to form a tubular valve cup containingY a' chamber [3 by providing' an internal' transverse wall.. Hw at a 1o peint spaced subjaeent tothe mouth of the pipe Ir, the outer diameter of said cup above" said transverse wall being the same as that" of the pipe HV and the `upper part of said Vcup beirigeilternally screwthreaded and having screwed 20 thereonto the tubular cap structure i4;

The valve cup chamber I3- is provided with a threaded inlet port I5 in the transversely extending bottom portion `thereof in Vaxial `alinement with the pipe II` and into said. `port Ais 2.5 screwed downwardlyy the tubular portion I6 o the combined screw and gasket washer, by means of which the valve seat gasket washer' IT, thehead of the screw, is secured to the bottom of the cup chamber; In the 4wallfof sai-d cup at a point 150 slightly spaced above the transversewall Hw is arranged a circumferentially' spaced' series ofA radially extending passages i8.

Thecap structure I4, subiacent to its threaded portion is outwardly bulgedthereby providinga i semi-circularly shaped.` circumferential passaga way I9 intol which the water discharges from the f passages I8 and below said passageway said` bulge terminates in a downwardly directed skirt z the innerperiphery of which is slightly spaced away lo` from the external' periphery of the pipeV I I there- 1 by providing an annular channel` 2|: ,through which the water flows `irorrr the" passageway I9 intothetank. j The upper part oi the cap structure I4 is dia- 45 metrically contracted to form an axial tubular extension 22 and also to form a downwardly facing annular shoulder 23 which overhangs the valve cup chamber I3. Within said cap structure is mounted a vertically slidable plunger valve 50 25, the upper part of which has a working fit within the tubular extension 22. The lower portion of the plunger valve 25 which remains within the valve cup chamber I3 during the operation of the l device has a diametrically enlarged part 26 which forms an annular extension or broad circumfercompletes its closing movement.

At one side, on a level with its annular channel I9, the tubular structure I4 is furnished with a lateral extension 3|. A horizontally directed passage 32 extends passage 35with which said outlet 33 is in axial alinement. With the opposite end of said passage 35 communicates the re-iill tube I0. Since this anti-syphon 446,726; nies June 12, 1942, of which this appui cation is a continuation-impart and which issued as Patent No. 2,302,274, on November 17, 1942,

vfurther description thereof is unnecessary.

the upper portions of said `two The rod structure 43 carries a float midlength 4l normally Wrench to said head it is necessary to make the head small enough to leave a space therearound wall of the cup, as shown in otherwise cross-sectionally contoured to receive a properly shaped wrench, in which case this member may be provided with a circular head as large in diameter as the internal diameter of the cup. Said member l1 should be made of hard be possible if the gasket and its attaching element were made in separate pieces.

In the operation of the device, when the valve instead of striking against a gasket of any kind and wearing out the material thereof.

The operation of the device is not herein described in further detail as it to which the invention pertains,

already well known, are described in my Patent No. 2,302,274, already herein referred to.
